SAFETY DEVICE FOR ANTIREFILLABLE BOTTLES.

To all whom it may concern:

Be it known that I, JEAN BAPTISTE ARSAO, a French citizen, residing at Le Puy, Department of Haute Loire, in France, have invented new and useful Improvements in Safety Devices for Antirefillable Bottles, of which the following is a full, clear, and exact description.

This invention relates to safety device for anti-refillable bottles. known a great many systems of devices for making bottles anti-refillable and for indicating the fraudulent attempt to fill any liquid into such a bottle. There have become known some systems in which floats are made use of which being influenced by a spring descend along a toothed rack to indicate the level of liquid contained in the bottle; there further are known various systems using stoppers with grooves and influenced by springs which although they permit to pour out the liquid from the bottle, effectively prevent the introduction of any instrument or device for keeping back the floater with a View to fraudulently fill liquid into the bottle.

The devices of known construction generally are very complicated and expensive or, if they are cheap to construct, they are not thoroughly reliable.

The present invention has for its object, to improve the construction of such a device destined to prevent the fraudulent filling in of a liquid into bottles or other vessels, the construction of the device being based upon the floater system, comprising a central rod with springs and a floater without springs or pawls and of a grooved core, the grooves of which are helicoidal and which comprises a transverse spring and completely prevents any interference with the position of the floater.

The improvements according to the present invention aim at rendering the device more simple and to prevent any displacement of the floater during transport.

The invention is hereinafter more fully described, reference being had to the accompanying drawings, in which various forms of execution of the safety device are shown by way of example.

Figure '1 represents in vertical section a bottle with the safety stopper. Fig. 2 is a horizontal section through the core of the safety device and the bottle-neck on line AB of Fig. 1.

Specification of Letters Patent.

Application filed October 6, 1909.

There are already Patented May 3, 1910.

Serial No. 521,348.

The safety device essentially comprises a core, a central rod, a floater and wires which maintain said floater in a position close to the core as long as the bottle has not been opened.

The core 1 is preferably made of glass and of cylindrical shape, it carries upon its surface a certain number of helicoidal grooves 2 of any convenient cross section through which the liquid 3 flows out of the bottle 4:. The core 1 is further provided with a circular groove 5 and with a. transverse channel 6 destined to receive a spring 7 whose ends 8 are both bent. The core 1 further shows a cavity 9 for the central rod 10. The bottle 4: which may be of any shape preferably has an indentation 11 at the bottom for thereception of the lower end of rod 10, the neck 12 of the bottle having an inner groove 13 for the reception of the ends 8 of spring wire 7. A core 1 as described and shown can also be used with bottle necks which have no groove 13, in which case the bottle neck ought however be slightly enlarged toward the bottom of the bottle.

The bottle can be stopped by means of a stopper 14 of any convenient shape, which however preferably is of circular cross section. The central rod 10 is also preferably of circular cross section and has laterally extending thorns or flaps 15 (Fig. l) which act like springs and are arranged along the entire length of the rod.

The floater essentially consists of a cylinder of cork 17 perforated in the center for the rod 10. The floater 17 can be covered with and maintained by flanged plates 18 with eyes 19 or it may be used in its original state or with any suitable envelop. The floater can descend by its own weight and be drawn along by the liquid but the thorns 15 of the central rod 10 effectively prevent the floater from moving upward. The floater 17 is attached by wires 22 whose ends are simply picked into the cork or attached to the floater in any other suitable manner so that they can be easily removed from the same. The upper ends 24 of the wires are located in the grooves 2 of the core 1 and they are attached above said core to the stop per proper 14.

To insert the safety device in a bottle neck one proceeds as follows: The bottle a is filled 'with the liquid whereupon a rod 10 with its floater 17 is inserted in the indentation 9 of the core 1, the wires 22 being placed in the helicoidal grooves of said core. The core 1 is then inserted in the bottle neck 12 until the bent ends 8 of the spring 7 get into the circular groove 13 of the bottle neck, which is finally stoppered. If there is no circular groove 13 in the bottle neck, the core has to be pushed in until the lower end of the rod 10 touches the bottom of the bottle. In either case the pressure of spring 7 will prevent the removalof the core 1 from the bottle neck without brea kingthe bottle.

The safety device operates as follows: In opening: the bottle the wires 22 are pulled out, the floater 17 being thus released so that itcan adopt its normal position and float upon the liquid. According to the liquid being poured out, the level 25 of the liquid sinks and the floater l7 descends indicating always the amount of liquid contained; in the bottle. The floater cannot ascend as it is bound'to'butt against the thorns 15 of'rod 10. If any liquid should be fraudulently added, the floater would be submerged and clearly indicate the fraud. It further is impossible to intentionally alter the position of said floater, as the helicoidal grooves 2 prevent any access to the central rod 10.

I claim A- safety device for preventing fraudulent addition of any liquid in any vessel, comprising a core having helicoidal grooves, a transverse channel, a circular groove and a spring in the said channel, a central rod having laterally projecting thorns which act like springs and whose ends'are turned down, a floater loosely mounted on said central rod so that it can freely turn and descend on the same but is prevented from ascending by said lateral thorns, substantially as described and shown and for the purpose set forth.
